Exposition Corridor Transit Project Phase 2Final Hazard Analysis Report

1 August 2011

1.0 INTRODUCTION

1.1 Overview of the ProjectThe Expo Phase 2 light rail transit (LRT) project Final Environmental Impact Report (FEIR) wascertified by the Exposition Metro Line Construction Authority (Expo Authority) Board on February4, 2010 under the California Environmental Quality Act (CEQA). As a result of this action, theengineering and construction of this project commenced. Elements of construction may begin inearly 2012 followed by completion and opening of the project in late 2015. Note that once theproject is completed and accepted, the Expo Authority will hand over the project to the LosAngeles County Metropolitan Transportation Authority (Metro) for operation and maintenance.

Expo Phase 2 is located on the Westside of Los Angeles, extending approximately 6.7 milesfrom the Expo Phase 1 terminus at the Venice/Robertson Station in Culver City to Santa Monica.The project area is generally bounded by Santa Monica and Pico Boulevards on the north, LaCienega Boulevard on the east, Washington Boulevard on the south and the Pacific Ocean onthe west. Major freeways present in the study area include Interstate 10 (I-10) running east towest and Interstate 405 (I-405) crossing north to south through the corridor. Major east/westarterials include Santa Monica, Olympic, Pico, Venice and Washington Boulevards. OverlandAvenue, Sepulveda Boulevard, Bundy Drive, Lincoln Boulevard and Ocean Avenue traverse theproject area north to south.

The proposed operating plan for Expo Phase 2 provides continuing service from the Expo Phase1 terminus in Culver City to 4th St/Colorado in Santa Monica. From Culver City, the LRT wouldrun in an exclusive LRT right-of-way for approximately 5.5 miles. The LRT alignment would thendiverge from the right-of-way east of 17th Street and Colorado Avenue, where it would thenoperate within Colorado Avenue for approximately 1.2 miles westerly toward 4th Street. Theestimated one-way travel time from the Expo Phase 1 terminus to 4th St/Colorado is 19.5minutes, which equates to a 20.3 mph average operating speed.

The LRT will operate with Automatic Train Protection (ATP) as now operated on the Metro Blue Lineand the Pasadena Gold Line. ATP will be installed and operated from the Expo Phase 1 terminus tojust east of 17th Street in Santa Monica, as required. All of the at-grade crossings in this segmentwill have automated crossing controls and features such as the following: vehicle approach anddeparture gates, audible sounds, pedestrian approach gates and emergency exit swing gates at thesidewalk crossings, flashing lights, fencing, accessible features for blind pedestrians, and activatedelectronic no turn symbol signs. From 17th St. to 5th St./Colorado Ave., the LRT will be street-running(CPUC GO 143-B, Section 9.04b4). In this section, trains will operate at a speed no greater than theposted vehicle speed. Each grade crossing will have traffic signals for motorists and pedestrians,appropriate vehicle and pedestrian signage, limited left turn movements, striping and dedicated trainsignals (lunar white bar indications) for train operators. To further enhance safety, the gradecrossings will have train-actuated LED warning signals to alert motorists and pedestrians ofapproaching trains.

1.2 PurposeThe California Public Utilities Commission (CPUC) requires identification of potential grade crossinghazards and proposed mitigations for new light rail systems and extensions per GO 164-D, Section3.2.f. The purpose of this report is to fulfill the CPUC's requirements and present the results ofanalysis for the Expo Phase 2 project. The contents of this report are as follows:

3.0 GRADE CROSSING ANALYSIS

3.1 Overview of Light Rail Operation Potential HazardsExpo Phase 2 will provide maximum peak-service headways of 5 minutes with train operationscommencing at about 4 AM and continuing until about 2 AM seven days a week, consistent withhours of operation of the Metro system. Implementation of the proposed project could create thepotential for increased safety risks due to the introduction of a new LRT within or adjacent toexisting streets. However, the LRT would comply with CPUC and Metro design requirements toensure controlled access across the tracks. While the risk of collisions between motorists,pedestrians, and LRVs cannot be eliminated, Metro has adopted rules and regulations that areintended to improve the overall safety of LRT operations.

Additional safety requirements include train speed restrictions, emergency braking requirements,and appropriate barriers/signage/gates to discourage pedestrians and motorists from crossingthe tracks where not allowed. The installation of warning devices and the design of the crossingsalong the LRT will be in accordance with the requirements of CPUC General Orders and industrypractices. As required by CPUC GO 143-B, Section 7.08, the LRT would be designed to includeautomatic crossing gates and pedestrian warning signals installed whenever the alignment(exclusive or semi-exclusive) crosses a street at grade. Section 6 of the Metro Design Criteriaalso provides further direction and requirements with respect to crossing gates and signagerequirements to ensure the continued safety of local pedestrians.

This report provides the analysis of potential hazards of each grade crossing and develops measuresto mitigate those hazards. It should be recognized that while the design will include the appropriatemitigations, it does not guarantee that accidents will not occur. This is because motorists andpedestrians behavior and their obedience to the law is a key factor in preventing accidents. If themotorists or pedestrians do not heed the active and passive warnings provided for their safety,accidents may occur.

The hazard analysis began during the Environmental Impact Report (EIR) process in 2007whenthe Expo Authority used the Metro Grade Crossing Policy for Light Rail Transit (December2003) to analyze all potential grade crossings in order to initially determine at-grade and gradeseparated configurations. See Appendix D for the Conceptual Engineering FEIR drawings issuedDecember 4, 2009. There was extensive coordination with the City of Los Angeles Department ofTransportation (LADOT) and in order to reach a consensus, additional studies and discussionswith LADOT occurred in response to their DEIR comments. The findings from these studies anddiscussions are summarized in the October 15, 2009 letter from LADOT; see Appendix E. In theletter, LADOT concurred with the Expo Authoritys at-grade and grade separatedrecommendations and acknowledged that CPUC would ultimately approve the proposedconfigurations.

On December 4, 2009, the CPUC also issued a letter to the Expo Authority; see Appendix F. Thisletter acknowledges the extensive coordination and consultation by the Expo Authority with theCPUC, LADOT, and the City of Santa Monica in response to the CPUC and other comments onthe DEIR. Further, the CPUC recognizes the additional work and analysis that was conducted onthe crossings, which resulted in proposed project revisions and mitigation measures to furtherreduce impacts identified in the EIR. Accordingly, they state that the Expo Authority has beenresponsive to issues raised by the CPUC staff and LADOT concerning the impacts of theproposed crossings. Last, the CPUC also acknowledges that they have not made a finaldetermination regarding compliance with CPUC regulatory requirements, which would be made


6 August 2011

after certification of the FEIR and completion of the CPUC Rail Crossing Hazard Analysisprocess outlined in GO 164-D. This report fulfils this requirement.

3.2 Approach to Identifying Hazards

The analysis evaluated the following areas of potential hazards for each proposed grade crossingand documented the findings in the Hazard Analysis Matrices (Appendix A):

Train and roadway speed;

Skewed grade crossing;

Restricted pedestrian and/or vehicle sight distance;

Unsafe right or left turn from intersection/driveway onto or across a grade crossing;

Automobile traffic queue from nearby controlled intersection backs up across at-gradecrossing or from the at-grade crossing back to a nearby controlled intersection;

Vehicle driven around downed crossing gates;

Parallel roadways and driveways to tracks;

Pedestrian crosses tracks with train approaching;

Potential pedestrian surges;

The potential hazard areas were developed from past design and operation experiences fromother similar LRT projects; specific site inspections of the potential crossings; and, input from theCPUC, Metro, Cities of Los Angeles and Santa Monica.

3.3 Hazard Analysis Recommendations

The Hazard Analysis Matrices also provide details of proposed methods of controlling theidentified hazards. These proposed mitigations were also developed from past experiences alongwith coordination by the Expo Authority with the CPUC, Metro, Cities of Los Angeles and SantaMonica. Also refer to the Grade Crossing Concept Drawings that include the mitigations toaddress the identified hazards; see Appendix B.

The following events summarize the development of this Final Hazard Analysis Report:

4.0 SUMMARY AND CONCLUSION

Through the steps identified in Section 3.3 above, the potential hazards associated with eachproposed grade crossing have been assessed and proposed mitigations identified. As shownabove in Table 1 and presented in the attached Appendices A and B, the Expo Authorityproposes to:

1. Close six vehicular grade crossings

2. Grade separate eleven crossings (of which three are existing)

3. Construct nine at-grade crossings

4. Construct seven street-running crossings (of which two include pedestrian only gatedcrossings in addition to the adjacent vehicular crossings)

To date, there have been several meetings held with the appropriate parties to discuss theseareas in order to reach a consensus. As defined in the GO-164D, Field Diagnostic meetings wereheld with the CPUC, Metro, and Cities of Los Angeles Santa Monica after the Draft HazardAnalysis Report was submitted to the CPUC in June 2010. The attached updated HazardAnalysis Matrices and Concept Drawings (Appendices A and B) along with the Field and OfficeDiagnostic Meeting Notes (Appendix C) reflect the input provided to date. Ultimately, after thisreport is approved by the CPUC, the grade crossing configurations and their mitigations will beincorporated into the project design as such.
